According to a young man his Fiance accept to marry him because of his Surname..Please read below ..

"I read a conversation on my fiancee's Whataspp chat. She told her best friend that the only reason she wants to marry me is because of my surname. My surname is Anthony. She said she wants an English surname and I am the only one out of all her suitors that has one and that's why she chose to marry me. I have never heard of anything more stupid and callous and I am very upset. Who chooses a life partner because of their surname? I feel like calling off the engagement but should I talk to her first?
